refactor: Phase 109後のコード整理・改善(セットA/B/C完全実装)

全セット実装で総95行の純削減を達成(190削除, 95追加)

## Set A: Quick Wins (55行削減)
- FileBox caps check を check_write_capability() ヘルパーに統一
- is_required_in() から冗長な local variable 削除
- 未使用の CoreServicesConfig::from_env() 削除

## Set B: Architecture Refinement (65行削減)
- provider_lock の責務を「登録」のみに限定(init_* メソッド削除)
- PluginHost を initialization hub に統一
  - profile-aware provider 初期化を一元化
  - Default/NoFs の両 profile に対応
- FileBox::new() を Result-based に改善(Fail-Fast)
- delete()/copy() デッドコード削除(実装なし)
- PluginRegistry skeleton 削除(Phase 92 未実装プレースホルダ)

## Set C: Future-Proofing (+36行, 46追加/10削除)
- RuntimeProfile ドキュメント大幅拡充
  - 現在のプロファイル(Default, NoFs)の詳細説明
  - 将来のプロファイル(TestMock, Sandbox, ReadOnly, Embedded)を明示
- PluginHost::new_skeleton() 削除

## 設計改善

1. **責務分離の明確化**:
   - provider_lock: 登録のみ (set/get)
   - PluginHost: initialization hub (profile-aware setup)
   - initialize_runtime: env読み込みのみ

2. **Fail-Fast 原則の強化**:
   - FileBox provider missing → 即座にエラー(Default profile)
   - new() でパニック vs try_new() で Result

3. **将来への足がかり**:
   - Profile システムは拡張可能に設計
   - TestMock/Sandbox/ReadOnly/Embedded への対応準備完了

テスト:
- 既存テスト: 25/25 PASS 
- ビルド: SUCCESS 

ファイル変更:
- src/boxes/file/mod.rs (-58)
- src/runtime/core_box_ids.rs (-6)
- src/runtime/mod.rs (-23)
- src/runtime/plugin_host.rs (-90)
- src/runtime/provider_lock.rs (-62)
- src/runtime/runtime_profile.rs (+46)
